[FFmpeg-cvslog] r17994 - trunk/configure

[diego]

Author: diego
Date: Sun Mar 15 22:32:36 2009
New Revision: 17994

Log:
Disallow out-of-tree builds with config.h in the source tree.
A config.h present in the source tree takes precedence over a config.h
in the build tree, which can possibly result in an incorrect build.
